EETCEELL, AND

IMPROVEMENT iN mo To all whom 'it may concern: l

Be it known thatI, WILLTAM D. RTNEHAET, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Manufacturing Iron for Strap-Joints; and I do hereby declare that the following is a full and exact de scription thereof, reference being had to the aeeompanyin g drawings, and to the letters of reference marked thereon.

The nature ot' my invention consists in rolling iron out into rods or bars, said iron being so t'ormed in the rods or bars that by separating or cutting them into suitablelengths Jfor strap joints the forging process will be avoided.

To enable others skilled in the art to make and use my invention, I proceed to describe its construction and operation.

In the accompanying drawings, Figure I represents the apparatus or rolls used for making the iron into suitable forms. Fig. 2 represents an end view of said apparatus. Fig. 3 represents a transverse section ot` the die and roll which t'orm the strap for tbejoint. Fig. 4 represents a transverse section ot' the die and roll which form the key for the joint. Fig. 5 represents a transverse section of the die and roll which form the gibs tor the joint. Fig. Grepresents a piece or bar of iron formed for straps.

In the drawings, A replesents the base of the apparatus. D represents the housing for the rolls B and G. K represents the journal blocks or bearings for the rolls. The groove marked II in the roll B and the die marked E on the roll C form the iron for the strap of the joint. rPhe groove marked I in the roll B and the die marked F on the roll G 'form the iron for tbekeys. 'Ihe groove markedJ in the roll B and the die marked G form the iron for the gibs.

Theiron is rolled out into the desired lengths, l

width, and thickness in the ordinary manner and by the usual means, and nally passed through the grooves of the roll B and the dies ou roll G will give the iron the desired form. The form ofthe dies on the roll C will be seen by a reference to Figs. 3, 4, and 5. The rods or bars of iron, after being formed by the rolls B and C, are cut up into suitable length for straps, gibs, and keys. The part of the rod or bar between lines I and 2 in Fig. 4 will form a key, and cutting the rod or bar in Fig. 5 through at the points indicated by the lines 3, 4, and 5 it will i'orm gibs. By cutting the bar or rod represented in Fig. G through at the points represented by lines 6 and 7 straps will be formed.

The advantages of my improvement in iron for strap-joints are as follows:

First, I avoid the necessity' ot' all forging in making strapljoints.

Second, in making a large number of strapjoints ot' the same sizethe labor et bringing the various parts to a uniform size is entirely avoided.

Third, I obtain speed, ease, and strength in constructing, and save time and expense in titting and formingthe various parts of the strapjoint.

Having thus described the nature, construction, and operation of my improvement, what I claim as of my invention is A new article of manufactureto wit, iron for strap-joints-consisting of strap, gibs, and key, said iron being rolled in the t'orm herein described and represen'ed, and for the purpose set forth.
